Supply original MC74HC165ADTR2G, Logic - Shift Registers, by ON Semiconductor

8−Bit Serial or Parallel−Input/Serial−Output Shift RegisterHigh−Performance Silicon−Gate CMOS
The MC74HC165A is identical in pinout to the LS165.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.This device is an 8−bit shift register with complementary outputs from the last stage. Data may be loaded into the register either in parallel or in serial form. When the Serial Shift/Parallel Load input is low, the data is loaded asynchronously in parallel. When the Serial Shift/Parallel Load input is high, the data is loaded serially on the rising edge of either Clock or Clock Inhibit (see the Function Table).
The 2−input NOR clock may be used either by combining two independent clock sources or by designating one of the clock inputs to act as a clock inhibit.
